Quality of survival of patients with brain gliomas treated with postoperative CCNU and radiation therapy.

This prospective randomized clinical trial compared the effectiveness of combined treatment with CCNU and radiation therapy to the use of radiation therapy alone for the postoperative management of supratentorial brain gliomas (67% anaplastic) in 198 patients. The results were evaluated with the aid of a specially developed weighted neuropsychological test battery providing single-value estimation of "life quality" of patients, as well as with a clinical performance scale. Based on these methods, it was established that patients improved within 6 months following therapy.
